Browser App Approach: Can It Be an Answer to the Challenges in Cross-Platform App Development? Volume 16, 2017 BROWSER APP APPROACH: CAN IT BE AN ANSWER TO THE CHALLENGES IN CROSS-PLATFORM APP DEVELOPMENT? Minh Huynh* Southeastern Louisiana University, [email protected] Hammond, LA USA Prashant Ghimire Southeastern Louisiana University, [email protected] Hammond, LA USA *Corresponding Author ABSTRACT Aim/Purpose As smartphones proliferate, many different platforms begin to emerge. The challenge to developers as well as IS educators and students is how to learn the skills to design and develop apps to run on cross-platforms. Background For developers, the purpose of this paper is to describe an alternative to the complex native app development. For IS educators and students, the paper pro- vides a feasible way to learn and develop fully functional mobile apps without technical burdens. Methodology The methods used in the development of browser-based apps is prototyping. Our proposed approach is browser-based, supports cross-platforms, uses open- source standards, and takes advantage of “write-once-and-run-anywhere” (WORA) concept. Contribution The paper illustrates the application of the browser-based approach to create a series of browser apps without high learning curve. Findings The results show the potentials for using browser app approach to teach as well as to create new apps. Recommendations Our proposed browser app development approach and example would be use- for Practitioners ful to mobile app developers/IS educators and non-technical students because the source code as well as documentations in this project are available for down- loading. Future Research For further work, we discuss the use of hybrid development framework to en- hance browser apps. Keywords browser-based apps, mobile app usage, app development, cross-platform web app, store-retrieve-display app, WORA, hybrid development framework.

Browser App Approach INTRODUCTION According to a recent study by Pew Research Center on Smartphone, nearly two-thirds of Americans are now smartphone owners. Among the smartphone owners, Millennials (ages 18-34) are by far the most technologically advanced user group, with a 95% cell phone ownership. Majority of the cell phones today are smartphones (Smith, 2015). Interestingly, this explosion of smartphones has caused some incredibly complex challenges for developers as well as Information Systems (IS) educators and students. One of such challenges is how to create apps that can run on so many different platforms and devic- es on the market. Take the app CamScanner Pro for example. To be successful, its developers, INTSIG Information Co., must develop the same app to run on the following: iOS for iPhone; An- droid for devices such as HTC Desire, Samsung Galaxy, Motorola Droid Razr; Blackberry OS for Blackberry line of smartphones; Windows OS for Microsoft and Nokia Windows-based phones. Be- sides these major operating systems (OS), there are also other OS such as BADA from Samsung, Palm OS, Open WebOS, Maemo, MeeGo, Ubuntu, etc. Not only the developers of CamScanner face different OS but they also have to deal with different hardware from competing manufacturers. What developers are facing are also manifested in what IS educators and students are struggling with, especially in acquiring and developing skills related to mobile web design and app development. The challenge is how to learn, understand, and apply something like mobile app development that has a steep learning curve, has no standard technology, and keeps on changing. This is simply because each mobile platform works differently due to its unique hardware and OS. As reported in previous works (Huynh & Ghimire, 2015; Joorabchi, Mesbah, & Kruchten, 2013; Native, web or hybrid mobile-app development, 2012), such a technical challenge makes teaching mobile apps programming languages and tools for native apps almost out of reach for non-technical students. For instance, the Java code written for an Android app has to be converted into the Objective-C code in order to run on an Ap- ple iOS device. For those IS educators, it has become difficult to teach mobile web design and app development courses because the learning curve is so steep and the technology is not standardized and keeps on changing. For IS students, the technical requirements are so broad because there are so many different platforms and hardware to deal with. Consequently, they are scared away from learn- ing and understanding about mobile web design and app development. In this paper, we set out to explore ways to overcome this challenge. Our work is based on the previ- ously published JITE:IIP article titled “Learning by Doing: How to Develop a Cross-Platform Web App” by Huynh and Ghimire (2015). Based on their prototype, we advance the project further by adding more features/functionalities to make the original web app better and more useful and con- ceptualizing the developing processes into an approach that could provide guidance for IS educators to teach and IS students to learn about app development. In this paper, we extended the previous work in three ways. The first is the additional features that we added to enhance the prototype and turned it into a fully functional app. The second is the redesign of the code so that it could be reused to create other apps. Finally, most important of all, is to leverage on the experiences learned and knowledge gained from the previous project to formulate a conceptual foundation for the browser app approach presented in this paper. Because of this extended work, we are able to propose a pos- sible approach to the nagging problem of dealing with many different mobile platforms and devices. Our proposed approach is based on three key premises: (1) viewing web browser as a platform, (2) relying on open-source technology standard, and (3) applying “Write once and run anywhere” con- cept to minimize the learning curve. Throughout the paper, we attempt to demonstrate that app de- velopment does not have to be time-consuming, highly sophisticated, and platform specific. Rather, we show how we went through the development of a series of mobile browser-based apps in a time- ly and efficient manner without a steep learning curve. One of our advocative premises is that there is an alternative approach to the native app development approach. We think that browser-based app may provide the answer to the cross-platform app challenge. Therefore, we organize our paper as 48 Huynh & Ghimire follows. In the first section, we highlight the previous development of the prototype called Student Services Web App and the on-going progresses. Next, we describe the major enhancements that we added to this Web App. These experiences lead us to the proposed approach for the design and de- velopment of mobile browser-based apps or browser apps in short. In the following section, we describe the proposed approach in action. This section illustrates the process of creating a new browser app based on the proposed approach. The subsequent section then provides technical details on how to practically set up an environment to run browser apps and to adopt the code to create more apps. This is then followed with a discussion section where we make the case for the browser app approach. Finally, the paper concludes with the highlights of the work, the potential contribu- tions, limitations, and future development work. THE CHALLENGE The explosion of smart devices has created some incredibly complex challenges for developers as well as to IS educators and students. Since tackling all these challenges is beyond the scope of our paper, we would like to zero in one specific challenge. That is how to design and develop apps to run on cross platforms. In the academic context, the focus becomes how to teach advanced web design for a mobile environment and, specifically, browser app development given many different platforms and devices. Let us first take a closer look at this challenge in the context of the following three factors: the com- plexity when dealing with cross platforms, the effect of large number of native apps, and the fast pace of technology obsolescence. The discussion of these three factors provides the backdrop for our proposed approach and our advocacy for browser apps in the later sections. The first crucial factor is the current existence of large number of different platforms and devices on the market. Among the major platforms are IOS, Android, Blackberry, and Window Phone. These platforms run on different devices that are manufactured by different companies. While the availabil- ity of different platforms and devices offer consumers a variety of choices, they put tremendous burden on individual app developers or smaller app development shops as well as IS educators teach- ing mobile app development. Each of these operating systems requires completely different develop- er tools and development frameworks.

    The Mobile Operating Systems Analysis 2012- 2017: Who wins: Android vs. iOS vs. Windows? 4.4.5 Middle East and Africa Mobile OS Sales Forecast 2012-2017 Dominated by the Symbian platform in 2012, visiongain believes that Android will pick up where the incumbent leaves off. Smart device sales in the MEA region will inevitably be driven by low- cost Android handsets from OEMs such as Huawei, ZTE, HTC, and Motorola. Windows and iOS will have a more pronounced impact on the Middle Eastern market than the African one, with higher sales volumes in countries such as Israel, the UAE, Bahrain, and Saudi Arabia. Visiongain forecasts this region to have relatively low smart device penetration in 2017, reaching sales of just over 107 million units that year. See Figure 4.31 and Table 4.25.

Games research firm Newzoo reckons roughly one-third of the planet’s population – that’s 2.6 billion people – will play mobile games this year. That number is projected to grow to 2.7 billion by 2021. Many are gaming fans, and many more are part of a new and captive audience forced by global events to practice social distancing and use their downtime to seek digital distractions. The outcome is a "bonanza" for gaming apps, an industry sure to experience a windfall of profits despite the tailwinds of a potential global recession. Overall, mobile gaming revenues are now set to top $100 billion this year, according to the latest data from app market intelligence provider App Annie and global research firm IDC. In total, the research concludes, mobile game spending will grow to more than 2.8x over desktop gaming and 3.1x more than home game consoles. ● Mobile gaming is the fastest growing segment and will account for 48% of all gaming revenues in 2020, up 13% from the previous year, thanks to blockbuster hits, including Fortnite, League of Legends and Pokémon Go.

    7 Critical Capabilities Your Mobile App Development and Deployment Platform Must Include Speed Mobile App Development and Ensure Wide User Adoption Executive Summary In today's mobile business environment companies are scrambling to quickly mobilize hundreds of B2B and B2E business processes or legacy applications. There are three main approaches developers can use to build mobile business apps: - Responsive web apps - Native app development - "Native quality" hybrid apps This whitepaper explains important differences between these three approaches, outlines 7 mobile capabilities that real-world business apps require today, and identifies the most productive development approach for getting these mobile business apps to market FAST. 1 | P a g e High Demand for Mobile Apps For competitive and productivity reasons, businesses and organizations are embracing mobile more than ever. Gartner forecasts enterprise application software spending to double from $300B in 2013 to over $575B by the end of 2018.1 Yet, Gartner also predicts demand for enterprise mobile apps will outstrip available development capacity by five to one.2 Forrester warns: “The CIO who fails in mobile will lose his job.”3 As a result, companies are trying to find new ways to enable their employees to develop business apps. Everyone from young IT or business workers with basic HTML5 skills, to IT developers with limited mobile experience and business analysts are exploring how to build apps to get routine things mobilized faster. Rising End-User Expectations Complicating the problem is the rising expectations of an increasingly mobile workforce. Employees are adopting mobile devices exponentially and demanding more business apps to do their work.
